45,000 Fish Dead: Sewer Overflow Ravages River

A recent report detailed a significant fish kill event on the Chattahoochee River, where an estimated 45,000 fish died. This ecological disaster was primarily attributed to a combined sewer overflow and stormwater discharge from Atlanta's West Area Tunnel. For over five hours, nearly six million gallons of untreated or minimally treated sewage and stormwater were released into Peachtree Creek.

The incident impacted a specific section of the Chattahoochee River in Georgia, from Peachtree Creek down to the City of South Fulton. Crucially, the fish kill did not extend to upstream recreation areas or downstream sections like West Point Lake or the river near Columbus. State officials observed increasing numbers of dead fish, a strong sewage odor, and excessive litter during their investigation.

Environmental organizations believe a confluence of factors, including low river flows due to drought, polluted stormwater, the sewer overflow, and treated wastewater discharges, created a 'perfect storm' for the fish kill. This event is considered the largest of its kind since 2011, when a different pollution incident killed 38,000 fish. The loss of these fish has been valued at $840,000.
